Fujifilm GFX Eterna 55 has a
102.0MP Medium format (44 x 33 mm ) sized BSI-CMOS sensor and features X-Processor 5 processor. On the other hand, Blackmagic PYXIS 12K has a
98.8MP Full frame (35.6 x 23.3 mm ) sized CMOS sensor .
Below you can see the GFX Eterna 55 and PYXIS 12K sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm GFX Eterna 55 and Blackmagic PYXIS 12K Cameras
As seen above, Fujifilm GFX Eterna 55 has a 1.8x Larger sensor area than Blackmagic PYXIS 12K. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Fujifilm GFX Eterna 55
or the
Blackmagic PYXIS 12K ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(Medium format versus Full frame),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
